Football: Diego Rossi's hat-trick leads LAFC to 4-0 win over DC United, Wayne Rooney shown red card

Diego Rossi had his first career MLS hat trick to help LAFC snap D.C. United's 15-game regular-season unbeaten streak with a 4-0 win on Saturday. Carlos Vela scored his MLS-leading seventh goal of the season in the 15th minute to give LAFC (5-0-1) a 1-0 lead. Rossi slipped a left-footer inside the near post in the 27th. Rossi first-timed a bending side-netter about five minutes later to make it 3-0 at halftime and capped the scoring in the 76th minute. Vela and Rossi have more goals (13) this season than any other MLS team. D.C. United (3-1-1) played a man down after Wayne Rooney, who came in among the MLS leaders this season in goals (four) and assists (three), was shown a straight red card in the 52nd, after video review, for a dangerous tackle on Rossi.
